Hypothesis: International law’s usual split between war and peace does not cover modern hybrid warfare. As shown by Schmitt et al. (2017) in the Tallinn Manual 2.0, cyber and Grey Zone attacks often stay below the level of an "armed attack," making it hard to identify the attacker and allowing states to break sovereignty rules without facing legal punishment (Bachmann, 2023; Mazarr, 2015).
